there is a lot that can be fixed within that team,
Samuel although he is an 85, he is rubbish, UP Silva is better, IF Mexes or UP Mexes is better, IF Gamberini is better, IF Nesta, etc.
Hamsik is terrible, push sneijder left CM, cambiasso middle CM and maybe Lavezzi (need to convert) right CM. Get De Rossi or IF Inler as a backup for cambiasso. Totti as a backup for sneijder and menez as a backup for lavezzi.
also sell 84 etoo, you have 3 strikers yet only one can play at a time, 2 should be more than enough and UP cavani > 84 etoo
de ceglie as backup LB and santon as backup RB
if you like to cross the ball a lot, then you really need to save up for Ibrahimovich, if you dont cross a lot then Milito and 86 Etoo are the best, followed by UP Ibra and UP Cavani.
